Push Button Load Switch

Our Push Button Load Switch features a Storage Mode to reduce Battery Drain during transit.

Normally battery power diminishes during transit time to the retailers and customers. Using the Load Switches saves power by disconnecting the system from the battery until the customer is ready to use the device.
