Switches are used when controlling circuits. Switches come in a variety of operation methods, sizes, and on/off control methods. Using the right switch for different scenarios can make circuit modifications aesthetically pleasing, efficient, and simple.
Common metal push button switches include self-locking switches, self-reset switches, rotary switches, lever switches, and lockable switches. Metal push button switches are compact, easy to install, made of metal, and can operate in voltages ranging from 9 to 220 volts. Their metallic appearance and the ability to customize them with personalized icons add a high-end, premium feel to any modification, making them suitable for a wide range of applications. Common applications include automotive modification, computer assembly, instrumentation, and electrical control. A self-locking switch is one in which, when pressed, a self-locking mechanism locks the button, preventing it from releasing. This activates the circuit and illuminates the switch indicator. Pressing the switch again releases the self-locking mechanism, causing the button to release, de-energizing the circuit and turning off the switch indicator. Self-locking switches are often used to control circuits that require continuous power, such as lights, motors, and fans.
A self-resetting switch is one in which, when pressed, the trigger mechanism contacts, energizing the circuit and illuminating the switch indicator. Once the switch is released, the trigger mechanism separates, de-energizing the circuit and turning off the switch indicator. Self-resetting switches are often used to control circuits that require only a short activation period, such as honking a horn, restarting a computer, or operating a warning light. A rotary position switch controls a circuit by rotating a knob, typically with two or three positions. In the initial position, the circuit is de-energized and the switch indicator is off. Rotating the knob to position 1 energizes the corresponding circuit, illuminating the switch indicator. Rotating the knob to position 2 energizes the corresponding circuit, illuminating the switch indicator. Rotary position switches are commonly used in situations where speed, brightness, temperature, and other adjustments are required, such as fan speed, washing machine speed, and air conditioner temperature.
A lever-type switch controls a circuit by moving a lever, typically with two or three positions. In the initial position, the circuit is de-energized and the switch indicator is off. Moving the lever to the first position energizes the corresponding circuit, illuminating the switch indicator. Moving the lever to the second position energizes the corresponding circuit, illuminating the switch indicator. Lever-type switches are commonly used in situations where switching between on and off or changing states is necessary, such as turning on a microphone, switching the tone of an electric guitar, or operating the instrument panel on a ship or airplane.
A lockable switch has an internal lock cylinder that requires a key to be inserted and rotated to unlock the circuit. Initially locked, the circuit is de-energized and the switch indicator is off. Inserting the key and rotating the lock cylinder unlocks the circuit, energizing the circuit and illuminating the switch indicator. Lockable switches are typically used in situations where high-security, high-security, power-on/off functions are required, such as sluice gates, electric switches, and hazardous equipment.
