Eaton E32 eSM (Electronic Switch Module) Multiplexed Rocker Switch

Above-Panel Multiplexed Master Module, LIN Sub-Bus, Communicates With Up To Seven Expansion Modules and Top, Center, and Bottom LED Lighting.

The Easton E32 eSM offers a high level of flexibility, the above-panel electronic multiplex switch module covers your wide range of switch and indicator applications using standard or custom graphics, as well as a full range of circuits and illumination options. The above-panel eSM E32 has top, center and bottom LED lighting with software that offers advanced circuit and lighting flexibility, including dimming and flashing options via J1939 CAN-bus communication.

The indicator bar can be lighted with up to four separate colors to indicate operational status, vehicle mode, and faults. All standard combinations of
maintained and momentary switch actions, matching indicator caps and dummy plugs, along with the complementary styled SVR electromechanical rocker switch are available to complete the offering.

Electronic Switch Modules and Vehicle Displays

Electronic Switch Modules (eSM) and the Electronic Vehicle Display (eVU) are custom ordered, application specific electronic communications products from Eaton’s vehicle and commercial controls catalog.

For additional product flexibility and differentiated operator control, the E31 Keypad eSM is designed to communicate with Eaton’s E32 and E33 sealed rocker.
