![]() ![]() Locking push button switches feature a mechanical locking function. Conversely, surface mounted types are designed to attach directly onto the surface of the board. Through-hole or thru-hole varieties are connected via a drilled hole on the printed circuit boards, with soldering applied to pads on the reverse side. These surface-mounted PCB switches are designed to fit directly over the top of the PCB. They are commonly used to power electronic devices within domestic and workplace settings. Reference should be made to the technical datasheet to identify the panel cut-out size. Panel push buttons are specifically designed for attachment to sturdy mountings. This illuminated functionality signals that the device is in the on or off state, or experiencing a fault. Some tactile switches also feature LED illumination. They require a relatively small amount of force for adjustment of the switch and typically make a clicking noise to indicate whether or not the power is circulating. Tactile Push Button SwitchesĪlso known as tact switches, these compact switches are commonly designed for mounting on PCB boards. They are commonly used for powering keyboards, keypads, and interface control panels. They operate through the process of user interaction and are commonly integrated on top of a printed circuit board. These circuit board switches restrict the circulation of electricity until the button is pressed. Some feature both the push to make and push to break variety, depending on the wiring of the switch. Common examples include doorbells, calculator buttons, and keyboard keys. The connection will be broken as the button is released. The push to make switch enables electricity to flow through the circuit whenever the two contacts are held in. The switch can remain on in either position, with the connection made and broken from separate devices. However, the flow will immediately be broken on pressing. Electricity can flow to the circuit when no pressure is applied to the button. ![]() ![]() Push to Break SwitchesĪlso referred to as normally closed (NC), push to break switches are the most commonly used variety, operating oppositely to latching and momentary types. They are often used for resetting small electronic devices. Miniature or micro push button switches are available from a variety of brands such as C&K. LEDs are another common feature, with the backlighting indicating the status of the device. The on button is typically green the off button red. Similar to the two-position variety, dual push button switches feature one button for electrical connection and one for disconnection. It is quite common for these switches to be encased in protective plastic, with a key being required for operation. These have two set positions for turning the connected device off-on. The buttons are often connected to Arduino circuit boards, enabling them to control the function of an array of equipment. With the support of an international community of creators, Arduino specialises in the development of easy-to-use hardware and software. Arcade gaming - these switches are often round and used to control elements of the game.Stopping machinery - distinctive switches are typically found on or next to industrial machinery, used to stop operation in the event of an emergency. ![]()
