Frequently Asked Questions
Q: What does "normally open momentary push button switch" mean?
A: A normally open (N/O) switch means the circuit is open (off) by default. When you press the button, the circuit closes (turns on) only for as long as the button is held. When released, it returns to the open (off) state. This is ideal for applications like horns, starter buttons, and pulse signals.
Q: What panel cutout size is required for this switch?
A: This switch requires a 12mm diameter panel cutout, which is a standard size compatible with most automotive dashboards, marine panels, and DIY project enclosures.
Q: Can this switch be used on boats or outdoor equipment?
A: Yes. The stainless steel construction makes this switch corrosion-resistant and well-suited for marine, outdoor, and automotive environments where exposure to moisture and vibration is expected.
Q: Does this switch come with pre-wired leads?
A: Yes. Each switch includes pre-welded cable leads, so no soldering is required. Simply connect the leads to your circuit using standard connectors or terminals for a quick and clean installation.
