  2. Commutator (electric) - Wikipedia

    en.wikipedia.org/wiki/Commutator_(electric)

    A commutator is a rotary electrical switch in certain types of electric motors and electrical generators that periodically reverses the current direction between the rotor and the external circuit. It consists of a cylinder composed of multiple metal contact segments on the rotating armature of the machine.

  3. Electromechanics - Wikipedia

    en.wikipedia.org/wiki/Electromechanics

    Strictly speaking, a manually operated switch is an electromechanical component due to the mechanical movement causing an electrical output. Though this is true, the term is usually understood to refer to devices which involve an electrical signal to create mechanical movement, or vice versa mechanical movement to create an electric signal.

  4. Relay - Wikipedia

    en.wikipedia.org/wiki/Relay

    Expected mechanical loads due to acceleration — some relays used in aerospace applications are designed to function in shock loads of 50 g, or more. Size — smaller relays often resist mechanical vibration and shock better than larger relays, because of the lower inertia of the moving parts and the higher natural frequencies of smaller parts ...

  5. Voltage regulator - Wikipedia

    en.wikipedia.org/wiki/Voltage_regulator

    Early automobile generators and alternators had a mechanical voltage regulator using one, two, or three relays and various resistors to stabilize the generator's output at slightly more than 6.7 or 13.4 V to maintain the battery as independently of the engine's rpm or the varying load on the vehicle's electrical system as possible.

  6. Switch - Wikipedia

    en.wikipedia.org/wiki/Switch

    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 ...

  8. Interlock (engineering) - Wikipedia

    en.wikipedia.org/wiki/Interlock_(engineering)

    The interlock consists of one or more switches that prevent both main power and generator power from powering the dwelling simultaneously. Without this safeguard, both power sources running at once could cause an overload condition, or generator power back-feed onto the main could cause the dangerous voltage to reach a lineman repairing the ...

  9. Telephone exchange - Wikipedia

    en.wikipedia.org/wiki/Telephone_exchange

    Electromechanical switching systems required sources of electricity in form of direct current (DC), as well as alternating ring current (AC), which were generated on-site with mechanical generators. In addition, telephone switches required adjustment of many mechanical parts. Unlike modern switches, a circuit connecting a dialed call through an ...
