Such a switch requires a depletion-mode MOSFET, which acts like a “normally-closed” SPST relay. In the past, the electronic industry has typically designed this type of circuit by using more power ...

The most common application of an automotive relay is to switch a high current circuit using a low current circuit ... relays are sometimes referred to as Single Pole Single Throw (SPST) relays, and ...

What are Printed Circuit Boards (PCBs)? PCBs are manufactured using CNC machining or chemical ... thermistors, and switches (reed, PTM, SPST, SPDT, toggle, microswitch, rocker, membrane, slide).

The addition of an extra contact to an SPST switch lets it turn off one circuit and turn on another. This makes it a single-pole double-throw (SPDT) switch. Double-throw switches can make ...

Q. What type of circuit breaker does the Code allow to be used for switching duty of lighting circuits? A. Circuit breakers used to switch 120V or 277V fluorescent lighting circuits must be listed and ...

A small protection device such as this dual SPST IC switch can provide major benefits and prevent further damage to sensitive front ends when faults occur. 1. The ADG7421F dual SPST switch ...
