Those two dimensions are the practical fitment checkpoints for this switch, especially where the rear of the panel is tight or where nearby wiring may limit space.\u003c\/p\u003e\n\u003cp\u003eCheck that your circuit is a 12V system and that the load falls within the 20A rating. The switch is a 1-pole, 2-position On-Off SPST unit, so it suits a straightforward single circuit control rather than multi-function switching.\u003c\/p\u003e\n\u003cp\u003eThe switch has 2 blade terminals, so the existing wiring needs to be suitable for that terminal style. If you are replacing an original switch, compare the part no. 56-90029BLR, the physical dimensions, and whether a non-illuminated switch is acceptable for the application.\u003c\/p\u003e\n\u003cp\u003eAs with any electrical component, the correct choice depends on the vehicle or equipment’s wiring arrangement, mounting hole size, and current demand. Matching the listed specifications is the safest way to avoid ordering the wrong switch, particularly when the original part is worn or unreadable.\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 56-90029BLR 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) 20, Voltage 12, Mount Diameter 12mm, Number of Poles 1, Switch Type Toggle, Weight .04kg, Product Group 1 AUTO ELEC ACCESSORIES.\u003c\/p\u003e\n\u003cp\u003eAdditional published details for cross-checking include Part No. 56-90029BLR, Brand REVOLUTION, Description Revolution Toggle Switch On\/Off SPST (Contacts Rated 20A @ 12V), Number of Terminals 2, Switch Action On - Off - SPST, Lamp Colour\/s Not Applicable, Mount Length 29mm, Number of Positions 2, Switch Illumination Non Illuminated.\u003c\/p\u003e\n\u003cp\u003eRevolution Toggle Switch On\/Off SPST (Contacts Rated 20A @ 12V).

These details form the core reference points used by parts interpreters when confirming the correct replacement.\u003c\/p\u003e\n\u003cp\u003eFor part number 56-90029BLR, 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 20 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\u003e\u003cstrong\u003eCompatibility note:\u003c\/strong\u003e Confirm compatibility by checking part no. 56-90029BLR, the 12mm mounting hole, 29mm mount length, 12V rating, 20A rating, and 2 blade terminal layout against your existing switch or panel opening before ordering.\u003c\/p\u003e\n\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003ch4\u003eWhat type of switch is this?\u003c\/h4\u003e\n\u003cp\u003eIt is a Revolution toggle switch with On-Off SPST action, meaning it is a single-pole, two-position switch for simple on\/off control.
