The step-by-step relay is a bistable relay made to achieve a fast load switching through the pressure of a button.
Designed to fit into a standard automotive relay socket, each time this relay receives a positive impulse on terminal T (6), the output status switches immediately between two different loads/plants, fed by the same circuit.
In fact, a changement of status happens on both terminals 53S (5) and terminal 1 (1). Relay has not memory.
This item can be supplied with a metal bracket.
