This circuit allows an SPST momentary pushbutton to act as a push-on push-off switch, using a DPDT latching (bi-stable) relay. It was originally intended to allow a single pushbutton switch on the ...

This is an improved version of Anthony Smith’s designs for a latch on/latch off switch (see the whole series below). The new design switches a 120VAC load, and includes several much-needed details on ...

For some of us, there are few sounds more satisfying than the deep resonant “thunk” of a high quality toggle switch slamming into position. There isn’t an overabundance of visceral experiences when ...

Push to make switch (PTM) is a momentary switch that closes the circuit only while pressed and is commonly used in doorbells and keyboards. Single pole, single throw switch (SPST) is a latching switch ...

Most switching power-supply controllers provide non-latching fault protection. Satisfying a requirement for a latchoff response to a fault often requires the addition of excessive and redundant ...
