It is supplied as a 22mm mount diameter switch with a 28mm mount length, which makes the mounting dimensions important to check before ordering.\u003c\/p\u003e\n\u003cp\u003eThis switch is identified as Part No. 91113BL and falls within the Auto Elec Accessories and Fuses Breakers Relays Switches product groups. For buyers replacing an existing switch, matching the 22mm mounting size, 2 terminals, and 1-pole layout is a practical first step in confirming suitability.\u003c\/p\u003e\n\u003cp\u003eBecause this is a reverse switch with momentary operation, it is best suited to applications that call for an Off - Mom On - SPST switching arrangement rather than a maintained on\/off control. The contact rating of 10A at 12V is a key specification to compare against the electrical load in the vehicle or equipment it is intended for.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCole Hersee reverse switch\u003c\/li\u003e\n\u003cli\u003eOff - Mom On - SPST action\u003c\/li\u003e\n\u003cli\u003eContacts rated 10A @ 12V\u003c\/li\u003e\n\u003cli\u003e22mm mount diameter\u003c\/li\u003e\n\u003cli\u003e28mm mount length\u003c\/li\u003e\n\u003cli\u003e2 terminals\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBrand: Cole Hersee\u003c\/li\u003e\n\u003cli\u003ePart No.: 91113BL\u003c\/li\u003e\n\u003cli\u003eProduct type: Switch\u003c\/li\u003e\n\u003cli\u003eSwitch type: Reverse\u003c\/li\u003e\n\u003cli\u003eSwitch action: Off - Mom On - SPST\u003c\/li\u003e\n\u003cli\u003eNumber of positions: 2\u003c\/li\u003e\n\u003cli\u003eNumber of poles: 1\u003c\/li\u003e\n\u003cli\u003eNumber of terminals: 2\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplication and Buying Notes\u003c\/h3\u003e\n\u003cp\u003eBefore buying, check the existing switch opening and confirm it accepts a 22mm mount diameter with 28mm mount length. These two measurements are the most direct physical checks provided, and they help avoid ordering a switch that will not seat correctly in the panel or dash.\u003c\/p\u003e\n\u003cp\u003eThe electrical side should also be matched carefully. This switch is rated at 10A @ 12V, so the current draw and system voltage should be compared with the job it is being asked to perform. A 2-terminal, 1-pole switch with Off - Mom On - SPST action is not the same as a multi-terminal or maintained switch, so the original function should be checked closely.\u003c\/p\u003e\n\u003cp\u003eIf you are replacing an existing part, use Part No. 91113BL and the switch description Off - Mom On - SPST as the main reference points. That combination is more reliable than relying on appearance alone, especially where similar-looking switches can differ in terminal count, mounting size, or operating action.\u003c\/p\u003e\n\u003cp\u003eThe switch is non-illuminated and has lamp colour listed as not applicable, so it should be chosen for applications where no indicator light is required. If an illuminated switch is needed for the job, this unit will not match that requirement and another part should be selected instead.\u003c\/p\u003e\n\u003cp\u003eAs with any electrical control component, confirm the wiring arrangement before installation. The two terminals and momentary operation matter, particularly where the switch is part of a circuit that depends on a brief contact rather than a latching function. Careful comparison now usually saves rework later.\u003c\/p\u003e\n\u003cp\u003eBefore supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.\u003c\/p\u003e\n\u003cp\u003eFor workshop, fleet, and equipment applications, accurate identification of part number 91113BL helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.\u003c\/p\u003e\n\u003cp\u003eRelevant published details for this unit include Type SWITCH, Unit of Measure EACH, Warranty One Year, Power Rating (Amp) 10, Voltage 12, Mount Diameter 22mm, Number of Poles 1, Switch Type Reverse, Product Group 1 AUTO ELEC ACCESSORIES, Part No. 91113BL.\u003c\/p\u003e\n\u003cp\u003eAdditional published details for cross-checking include Brand COLE HERSEE, Description Reverse Switch Off - Mom On - SPST (Contacts Rated 10A @ 12V), Number of Terminals 2, Switch Action Off - Mom On - SPST, Lamp Colour\/s Not Applicable, Mount Length 28mm, Number of Positions 2, Switch Illumination Non Illuminated, Product Group 2 FUSES BREAKERS RELAYS SWITCHES.\u003c\/p\u003e\n\u003cp\u003eReverse Switch Off - Mom On - SPST (Contacts Rated 10A @ 12V). Part number 91113BL should be checked first. Listed voltage is 12. Listed output rating is 10. These details form the core reference points used by parts interpreters when confirming the correct replacement.\u003c\/p\u003e\n\u003cp\u003eFor part number 91113BL, the normal identification sequence is part number, electrical rating, mounting arrangement, connector or terminal style, and pulley or drive details. Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.\u003c\/p\u003e\n\u003cp\u003eFor a switch in workshop, fleet, trade, agricultural, or construction service, the listed voltage 12 and output 10 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.\u003c\/p\u003e\n\u003cp\u003eWhere no verified application list is available, the part number, mounting details, connector style, and published specifications should be used as the primary selection criteria.\u003c\/p\u003e\n\u003cp\u003eIn the absence of a verified fitment list, the safest approach is to compare the removed unit directly with the listed product details. That includes checking the housing style, pulley layout, regulator arrangement, and any visible identification numbers before supply is approved.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCompatibility note:\u003c\/strong\u003e Confirm fitment by matching Part No. 91113BL, the Off - Mom On - SPST action, 2-terminal layout, and the 22mm mount diameter with 28mm mount length against the existing switch and application details before purchase.\u003c\/p\u003e\n\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003ch4\u003eWhat is the main switch action on this part?\u003c\/h4\u003e\n\u003cp\u003eIt is an Off - Mom On - SPST switch. That means it has a momentary on function rather than a maintained on\/off action.\u003c\/p\u003e\n\u003ch4\u003eWhat is the electrical rating?\u003c\/h4\u003e\n\u003cp\u003eThe contacts are rated at 10A @ 12V.

Both measurements should be checked against the existing panel opening and available space.\u003c\/p\u003e\n\u003ch4\u003eIs the switch illuminated?\u003c\/h4\u003e\n\u003cp\u003eNo. The switch illumination is listed as non illuminated, and lamp colour is not applicable.\u003c\/p\u003e\n\u003ch4\u003eWhat part number should be used for matching?\u003c\/h4\u003e\n\u003cp\u003eThe listed part number is 91113BL. Matching that part number, along with the 22mm mount diameter and Off - Mom On - SPST action, is the safest way to compare against an existing unit.\u003c\/p\u003e","brand":"COLE HERSEE","offers":[{"title":"Default Title","offer_id":56889025003680,"sku":"A5410052","price":71.5,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0275\/5058\/0875\/files\/VeeqGZw8YaMojlQY3NZhzQ.jpg?v=1775126682","url":"https:\/\/www.micksgonebush.com.au\/products\/a5410052-reverse-switch-off-mom-on-spst-cont","provider":"Micks Gone Bush","version":"1.0","type":"link"}
