Because your vehicle is continuously exposed to natures elements, we offer the latest in Eaton's multiplexed line of switch product, the E31 Keypad eSM. Eaton's E31 Keypad eSM multiplex switch module offers a flexible and sealed solution for high density switch requirements in severe environments. The keypad can be configured with any graphic or switch, as well as with customer defined illumination. For customers requiring additional switches, expansion modules can be used with no requirement for additional CAN nodes. For additional product flexibility and differentiated operator control, the E31 Keypad eSM is designed to communicate with Eaton's E32 and E33 sealed rocker expansion modules.
