In order to create a circuit of pass-through switches using a pulsed (bistable) relay, you need to keep in mind that such a circuit allows you to open or close an electric circuit with the help of a short pulse. To perform this scheme, you need to use special buttons that enable the relay to be activated.
Touch or mechanical buttons suitable for this use have a specific designation. For example, buttons marked IH mean a sensor button with a dry contact, that is, a button that works directly through an electrical contact. Buttons marked H can be either touch or mechanical, and are used in ordinary bell-type rotary switches.
Thus, the use of the corresponding buttons with the indicated designations ensures compatibility with the through-switch circuit, which is based on a pulse relay. This ensures reliable functioning of the circuit breaker system in a simple and efficient way.
