How to Check for a Magnetic Switch.
If your power tool utilizes spring-loaded or momentary push buttons for start and/or stop
operations (as opposed to a toggle switch or other mechanical switch), follow the procedures
below to confirm that your power tool switch is not a magnetic switch.
Note: This evaluation is for power tools with relatively simply on/off controls and not for evaluating
larger control systems. Before proceeding, confirm that the working area is free of hazards and
that it is safe to operate the power tool.
Step 1: Turn the power tool ON.
Step 2: While the power tool is ON and running, remove power by unplugging the power tool or
by switching-off power at an electrical disconnect switch or circuit breaker.
Step 3: Count to 5 then restore power by plugging-in the power tool or by switching-on power at
the disconnect switch or breaker.
Evaluate:
●
If the power tool automatically turns ON when power is restored, then your power tool
does not have protection from unintentional restarts. You do not have a magnetic
switch.
●
If the power tool remains off when power is restored and requires manual turn-on to
restart, then your power tool does have protection from unintentional restarts. It is likely
that you have a magnetic switch or other type of control installed. Contact MAKESafe
