How to choose the right microswitch model?
Size matters when selecting a microswitch. Switch size is directly related to its characteristics, including current range, travel, and operating force. For example, one of the smallest microswitches on the market today measures 0.50 inches x 0.236 inches x 0.197 inches (LxWxH). While this tiny switch is suitable for use in compact circuit breakers for detecting circuit status, it is typically capable of interrupting only 0.1 to 3 amps (A) and has a short stroke. Applications requiring higher currents usually require larger switches. For example, a microswitch used to detect liquid level in a tank application would need to be able to provide a large stroke and withstand high currents. Often in level switch applications, the switch is used to directly drive a pump and carry a high current. This requires a large microswitch rated at 20A or 25A at 125VAC or 250VAC. Tip: The smaller the switch size, the less travel and current it can break.
