I need an on/off type switch (spst) on a device that will be subject to high, continuous centrifugal force loads (500-1000G or 5000-10000 m/s2)).
Will your everyday, off-the-shelf switch handle this?

Are there certain types of switch (sliding, toggle, push on/off) that will likely handle the forces better? It seems not many datasheets have such a rating.

I'm interested in both quantitative and/or experienced-based answers (i.e. "here's a datasheet" or "well, I've used this in this situation before"). EE Stackexchange seemed like the best place to ask this.

EDIT: The switch will be used to turn on/off a wireless data device. The switch will effectively just be pulling an enable pin high, so it's handling 3.3 to 5V, 1-10mA. My concern rests mostly with undesired switching on/off due to the forces involved. Am I unduly concerned?

EDIT: I talked with a friend, and she happens to be involved in rocketry - another electronics in high-G situation (although 50-100G are more typical). She mentioned that for switches, Rotary, screw, or just twisting the wires together are considered reliable.

I'll probably go with a screw switch unless someone suggests something else.

  • \$\begingroup\$ @DKNguyen Yes, it won't be passing much current. Effectively just bringing a pin high. \$\endgroup\$

    \$\begingroup\$ Mounting the switch such that all moving parts move perpendicular to the radius of rotation seems like a reasonable option. That way the forces will all be directed perpendicular to the switch's moving parts. Rotary switches would probably make this easy, or right-angle slide switches. \$\endgroup\$
