Analogue switch
ELECTRONIC COMPONENT THAT BEHAVES IN A SIMILAR WAY TO A RELAY, BUT HAS NO MOVING PARTS
Power load switch; Analog switch; Bilateral switch
The analogue (or PETR) switch, also called the bilateral switch, is an electronic component that behaves in a similar way to a relay, but has no moving parts. The switching element is normally a pair of MOSFET transistors, one an N-channel device, the other a P-channel device.
