Solar charge controller with JST connector for Solar Panel up to 2.5 W; Battery Monitor; DS3231 Real Time Clock and Temperature sensor, clock backup powered by LiPo battery; On/Off switch. With the switch in Off position the solar charge circuit is still active and the RTC clock is still powered. ICSP programming header; Sparrow [193] Open Home ...
Monitors with built-in KVM switch functions More monitors had been included a built-in KVM switch to be able to have two computer systems (two upstream system connections) to share the monitor. However, since most of current monitors with KVM switch functions had been putting the only hub-class KVM switch with them.
All of the above examples, such as the remote control, digital clock functions, and—in the case of adapters—no-load power, can be switched off just by switching off the power point. However, for some devices with a built-in internal battery, such as a phone, the standby functions can be stopped by removing the battery.
Active crowbars use a transistor, gate turn off (GTO) thyristor or forced commutated thyristor instead of a thyristor to short the circuit. Active crowbars are commonly used to protect the frequency converter in the rotor circuit of doubly fed generators against high voltage and current transients caused by the voltage dips in the power network .

The most widely used electronic switch in digital circuits is the metal–oxide–semiconductor field-effect transistor (MOSFET). [2] The analogue switch uses two MOSFET transistors in a transmission gate arrangement as a switch that works much like a relay, with some advantages and several limitations compared to an electromechanical relay.
