It is a 12\/24V standard switch with 3 screw terminals, silver contacts, and a non-illuminated design for straightforward electrical control applications.\u003c\/p\u003e\n\u003cp\u003eThis switch uses a nickel-plated brass mounting stem with 15\/32-32 thread, a 12mm mount diameter, and a 6mm mount length. Those dimensions matter when you are matching the switch to an existing panel opening, bracket, or control face and need a clean, secure fit without altering the setup.\u003c\/p\u003e\n\u003cp\u003eAs a 1-pole toggle switch from Cole Hersee, part number 55021BL, it suits applications where momentary centre-return control is required on either side of the off position. The one year warranty is included, and the unit is sold each.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSPDT Mom On-Off-Mom On switch action\u003c\/li\u003e\n\u003cli\u003eRated 25A at 12V and 12A at 24V\u003c\/li\u003e\n\u003cli\u003e12\/24V standard heavy duty toggle switch\u003c\/li\u003e\n\u003cli\u003e3 screw terminals with silver contacts\u003c\/li\u003e\n\u003cli\u003eNickel-plated brass mounting stem, 15\/32-32 thread\u003c\/li\u003e\n\u003cli\u003eNon-illuminated toggle switch\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.: 55021BL\u003c\/li\u003e\n\u003cli\u003eProduct type: Switch\u003c\/li\u003e\n\u003cli\u003eSwitch type: Toggle\u003c\/li\u003e\n\u003cli\u003eSwitch action: Mom On-Off-Mom On - SPDT\u003c\/li\u003e\n\u003cli\u003eNumber of poles: 1\u003c\/li\u003e\n\u003cli\u003eNumber of terminals: 3\u003c\/li\u003e\n\u003cli\u003eNumber of positions: 3\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplication and Buying Notes\u003c\/h3\u003e\n\u003cp\u003eBefore ordering, check the part number 55021BL and compare the switch action with your current unit. The key detail here is the Mom On-Off-Mom On SPDT configuration, so the replacement needs to match both the switching pattern and the number of terminals, which is 3 screw terminals in this case.\u003c\/p\u003e\n\u003cp\u003eMeasure the panel opening and confirm the mounting details before fitting. This switch has a 12mm mount diameter, a 6mm mount length, and a 15\/32-32 threaded nickel-plated brass stem, so it is important that the hole size and available depth suit the existing installation.\u003c\/p\u003e\n\u003cp\u003eElectrical rating also needs to suit the circuit. The switch is rated at 25A at 12V and 12A at 24V, so it should be used in a circuit that falls within those limits. If the original switch was illuminated, this one will not replace that function because it is non-illuminated.\u003c\/p\u003e\n\u003cp\u003eThe silver contacts and heavy duty 12\/24V construction suit general automotive electrical control use, but the correct application still depends on matching the original wiring arrangement and terminal count. If the existing setup uses a different terminal layout, pole count, or momentary action, it should be checked carefully before purchase.\u003c\/p\u003e\n\u003cp\u003eFor any replacement job, comparing the old switch to the listed dimensions and ratings is the safest approach. Confirm the toggle style, the 1-pole setup, the 3-position action, and the mounting thread before installing to avoid unnecessary rework.\u003c\/p\u003e\n\u003cp\u003eIf you are replacing a failed switch rather than fitting a new control, inspect the connector type, wire condition, and panel space as well as the switch itself. That helps make sure the new Cole Hersee 55021BL can be installed cleanly and used within its stated 12V or 24V ratings.\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 55021BL 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) 25, Voltage 12, Mount Diameter 12mm, Number of Poles 1, Switch Type Toggle, Product Group 2 FUSES BREAKERS RELAYS SWITCHES.\u003c\/p\u003e\n\u003cp\u003eAdditional published details for cross-checking include Part No. 55021BL, Brand COLE HERSEE, Description Cole Hersee Toggle Switch Mom On - Off - Mom On - SPDT (Contacts Rated 25A @ 12V), Number of Terminals 3, Switch Action Mom On - Off - Mom On - SPDT, Lamp Colour\/s Not Applicable, Mount Length 6mm, Number of Positions 3, Switch Illumination Non Illuminated, Product Group 1 AUTO ELEC ACCESSORIES.\u003c\/p\u003e\n\u003cp\u003eCole Hersee Toggle Switch Mom On - Off - Mom On - SPDT (Contacts Rated 25A @ 12V). Part number 55021BL should be checked first. Listed voltage is 12. Listed output rating is 25. These details form the core reference points used by parts interpreters when confirming the correct replacement.\u003c\/p\u003e\n\u003cp\u003eFor part number 55021BL, 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 25 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 Please confirm fitment by matching the part number 55021BL, the Mom On-Off-Mom On SPDT action, the 3-terminal layout, and the 12mm mounting dimensions against your existing switch and application details before ordering.\u003c\/p\u003e\n\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003ch4\u003eWhat is the switch action of this Cole Hersee unit?\u003c\/h4\u003e\n\u003cp\u003eIt is a Mom On-Off-Mom On SPDT toggle switch with 3 positions and 1 pole.\u003c\/p\u003e\n\u003ch4\u003eWhat are the electrical ratings?\u003c\/h4\u003e\n\u003cp\u003eThe switch is rated at 25A at 12V and 12A at 24V.\u003c\/p\u003e\n\u003ch4\u003eHow many terminals does it have?\u003c\/h4\u003e\n\u003cp\u003eIt has 3 screw terminals.\u003c\/p\u003e\n\u003ch4\u003eIs this switch illuminated?\u003c\/h4\u003e\n\u003cp\u003eNo. The switch is listed as non illuminated.\u003c\/p\u003e\n\u003ch4\u003eWhat mounting details should I check?\u003c\/h4\u003e\n\u003cp\u003eCheck the 12mm mount diameter, 6mm mount length, and 15\/32-32 threaded nickel-plated brass mounting stem.\u003c\/p\u003e\n\u003ch4\u003eDoes this listing confirm vehicle fitment?\u003c\/h4\u003e\n\u003cp\u003eNo vehicle models are listed here.
