Designed specifically for PCB mounting, these switches have pins or leads that are soldered directly onto the PCB.
Momentary switches typically have single-pole, single-throw (SPST) or single-pole, double-throw (SPDT) contact configurations. SPST has a single circuit, while SPDT has two possible circuits.
The force required to press the actuator and activate the switch. Different switches come with varying actuation forces to suit different preferences.
The distance the actuator travels when the switch is pressed. This can affect the tactile feel of the switch.
The termination style refers to how the switch is connected to the PCB. Common styles include through-hole (pins go through the PCB and are soldered on the other side) or surface mount (soldered directly onto the surface of the PCB).
The expected number of cycles (presses and releases) the switch can endure before potential failure. This is an important factor in applications where the switch will undergo frequent use.
Momentary switches can have various actuator types, such as buttons, levers, or tactile domes. The actuator design can affect the user experience and application suitability.
Some momentary switches come with sealing or protection against environmental factors such as dust or moisture. This is important for applications in harsh conditions.
Momentary switches find use in a wide range of applications, including keyboards, electronic devices, control panels, industrial equipment, and more.
Some PCB mount momentary switches come with built-in LEDs for illumination. This is common in applications where visual feedback is needed.
