The Cole Hersee push button switch, part no. 90047BX, is an off-momentary on SPST switch rated at 35A at 12V. It is supplied as a non-illuminated switch with 2 terminals, 1 pole, and 2 positions, which makes it suitable where a simple push button control is required.
Mounting is via a 22mm diameter hole, with a listed mount length of 2mm. Those dimensions are important when checking whether the switch will physically suit the panel or console you are working with, especially where mounting space is limited.
This switch is listed under auto elec accessories and fuses, breakers, relays and switches. The operating action is off – mom on – SPST, so the button returns from the momentary position rather than staying engaged in that state.

Application and Buying Notes
Before ordering, confirm the panel opening is sized for the 22mm mount diameter and allow for the listed 2mm mount length. A switch can have the right electrical rating and still be unsuitable if the mounting hole, depth, or panel layout does not match.
The 35A at 12V contact rating is a key checkpoint for circuit suitability. It is always sensible to compare the switch rating with the intended load and wiring arrangement, rather than relying on the shape of the button alone.
Because this is an off-momentary on SPST switch with 2 terminals, it is intended for simple switching duties where the circuit only needs a single pole and a momentary action. If your application needs latching control, illumination, or more than 2 terminals, this model would not be the right match.
The switch is non-illuminated and lamp colour is not applicable, so it is best suited to installations where a lighted button is not required. Check the surrounding controls and the way the switch will be used so the final installation suits both function and visibility.
Part no. 90047BX is the most reliable identifier to compare against your existing switch, wiring notes, or replacement records. If the part number, action, terminal count, and mounting size do not line up, pause and verify before purchase.
Before 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.
For workshop, fleet, and equipment applications, accurate identification of part number 90047BX 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.

Push Button Switch Off – Mom On – SPST (Contacts Rated 35A @ 12V). Part number 90047BX should be checked first. Listed voltage is 12. Listed output rating is 35. These details form the core reference points used by parts interpreters when confirming the correct replacement.
For part number 90047BX, 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.
For a switch in workshop, fleet, trade, agricultural, or construction service, the listed voltage 12 and output 35 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.
Compatibility note: Confirm compatibility by matching part no. 90047BX, the off – mom on – SPST action, 35A at 12V rating, 22mm mount diameter, and 2-terminal layout against your existing switch or application details.
