Most DIP packages are secured to a PCB by inserting the pins through holes in the board and soldering them in place. Where replacement of the parts is necessary, such as in test fixtures or where programmable devices must be removed for changes, a DIP socket is used. Some sockets include a zero insertion force (ZIF) mechanism.
Eight switches offer 256 (2 8) combinations, which is equivalent to one byte. A tri-state type DIP switch can be in one of three positions (+, 0, −) which allows more codes than a binary DIP switch. For example, 8 pole tri-state DIP switches offer 6,561 (3 8) combinations/codes compared to 8 pole binary switches' 256 (2 8) combinations/codes ...
Switches can be designed to respond to any type of mechanical stimulus: for example, vibration (the trembler switch), tilt, air pressure, fluid level (a float switch), the turning of a key , linear or rotary movement (a limit switch or microswitch), or presence of a magnetic field (the reed switch). Many switches are operated automatically by ...
This type is the one mostly used for industrial assembly applications such as electronic assembly and small parts assembly. Brushed electric motors and more efficient brushless motors are used. The torque ranges typically from 0.02 N⋅m to at least 27 N⋅m, [ 1 ] with speeds of up to 2,000 revolutions per minute (rpm).

A Single-Pole, Single-Throw (SPST) mercury switch on millimetre graph paper, device length approximately 1.5 cm Another mercury switch design. A mercury switch is an electrical switch that opens and closes a circuit when a small amount of the liquid metal mercury connects metal electrodes to close the circuit. There are several different basic ...
