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 ...

Low-current, momentary action pushbutton switches, such as PCB-mount ‘tactile’ types, are cheap, and available in an abundance of different styles. Latching types, on the other hand, are often larger, ...

When we first saw [Maarten Tromp]’s article about a “momentary latching switch” for guitar effects pedals, we have to admit to being a bit confused. When it comes to push-button switches, “momentary” ...

Camden Door Controls, a premier provider of door activation and locking devices, has added the new CX-LRS series latching relays, enabling the use of momentary ‘request for assistance’ switches, to ...

Most remote controls provide ample momentary closures for a command, but there are times when a maintained closure is needed. This circuit requires a momentary closure for the on command and momentary ...

Designed for the electric power industry, the Series 24 and 31 latching switch relays (LSRs) are used to open or close and maintain up to 20 contacts and can be operated either manually or remotely.

With this circuit, a single transmitter and simple set of user pushbuttons can initiate one of four different outputs, two at each of two remote receivers with very different applications. The ...

Omron Electronic Components has added to its range of latching power relays with devices that have interfaces for electric vehicle (EV) charge stations, PV inverters and lighting control. Omron ...
