It uses 3 terminals, has 2 positions, and is listed as a rocker type switch in the supplied product details.\u003c\/p\u003e\n\u003cp\u003eWith a 12mm mount diameter and 4mm mount length, this switch suits installations where the panel opening and mounting depth need to be checked before purchase. The unit weight is 0.03kg, and it is supplied as an individual switch, sold each.\u003c\/p\u003e\n\u003cp\u003eFor buyers working on 12V electrical accessories, the key identifiers here are the OEX brand, part number ACX3748BL, and the 20A current rating at 12V. The lamp colour is green, and the switch is described as illuminated, which may be useful where visibility of the switch position matters.\u003c\/p\u003e\n\u003cp\u003eA note is included for 24V applications: use Part No. ACX3912 resistor with the switch. That detail is important because the switch itself is specified for 12V, so application voltage needs to be confirmed before fitting.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eOEX push button switch\u003c\/li\u003e\n\u003cli\u003eOn-Off SPST action\u003c\/li\u003e\n\u003cli\u003e12V rated switch\u003c\/li\u003e\n\u003cli\u003eContacts rated 20A @ 12V\u003c\/li\u003e\n\u003cli\u003eGreen illuminated switch\u003c\/li\u003e\n\u003cli\u003e3 terminal design\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBrand: OEX\u003c\/li\u003e\n\u003cli\u003ePart No.: ACX3748BL\u003c\/li\u003e\n\u003cli\u003eProduct type: Switch\u003c\/li\u003e\n\u003cli\u003eSwitch action: On - Off - SPST\u003c\/li\u003e\n\u003cli\u003eVoltage: 12V\u003c\/li\u003e\n\u003cli\u003ePower rating: 20A\u003c\/li\u003e\n\u003cli\u003eNumber of positions: 2\u003c\/li\u003e\n\u003cli\u003eNumber of poles: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplication and Buying Notes\u003c\/h3\u003e\n\u003cp\u003eBefore ordering, check the panel opening size and mounting space against the 12mm mount diameter and 4mm mount length. Those measurements are the most practical confirmation points for whether the switch will physically suit the location you have in mind.\u003c\/p\u003e\n\u003cp\u003eElectrical load matters as much as the hole size. The switch is rated at 20A at 12V, has 3 terminals, and is a 1-pole SPST on-off switch, so it should be matched to the circuit design and current draw of the accessory being controlled.\u003c\/p\u003e\n\u003cp\u003eIf the application is 24V, the supplied note states that Part No. ACX3912 resistor is used with the switch. That means the 12V rating should not be ignored, and the vehicle or accessory voltage should be confirmed before installation.\u003c\/p\u003e\n\u003cp\u003eThe green illumination is part of the product spec and may help with switch visibility, but it should not be treated as a substitute for checking circuit compatibility. Where a switch is being replaced, compare the old unit’s terminal layout, mounting size, and switching action with ACX3748BL before purchase.\u003c\/p\u003e\n\u003cp\u003eThe one year warranty applies to the product as listed, but warranty support does not replace the need to verify fitment and voltage suitability. For electrical accessories, the safest approach is to match the part number, mount dimensions, and switch action first.\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 ACX3748BL 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, Note NOTE: For 24V applications, use Part No. ACX3912 resistor with the switch, Number of Positions 2, Switch Illumination Illuminated, Product Group 1 AUTO ELEC ACCESSORIES.\u003c\/p\u003e\n\u003cp\u003eAdditional published details for cross-checking include Part No. ACX3748BL, Brand OEX, Description OEX Push Button Switch On\/Off SPST 12V Green Illuminated (Contacts Rated 20A @ 12V), Number of Terminals 3, Switch Action On - Off - SPST, Lamp Colour\/s Green, Mount Length 4mm, Number of Poles 1, Switch Type Rocker, Weight .03kg.\u003c\/p\u003e\n\u003cp\u003eOEX Push Button Switch On\/Off SPST 12V Green Illuminated (Contacts Rated 20A @ 12V).
