the request of our customers we have now produced a high current, solid state switch
for use with Wild Thumper products. Although designed specifically for the Wild Thumper
chassis’s this switch can be used with any robot that needs to switch high currents.
Solid state switches are small, quiet, have no moving parts and do not suffer from arcing,
burnt contacts or fused contacts.
As the onboard switch may not always be convieniently located there is now a socket so
that an external low power switch can be connected. Just leave the onboard switch in the
“off” position to use the external switch.
This switch can also be controlled via a computer. With the grounds connected and at
least 1V applied to the “+” input the switch will be turned on. Leaving this pin open circuit
or grounded will turn the switch off.
Battery voltage: 6V -24V
Current rating: 10A continuous – No heatsink
Current rating: 30A continuous – Chassis used as heatsink with heat transfer compound.
Current rating: 60A continuous – Heavy duty heatsink, fan and heat transfer compound.
Digital input: 1V – 24V
When used with Wild Thumper chassis’s the switch uses the aluminium chassis for a
heatsink giving it a 30A continuous rating. Under normal operating conditions the 6WD
chassis should only draw about half of this.

Mounting on Wild Thumper chassis:
The FET’s used on this switch are fully insulated to simplify the mounting procedure. A
small amount of heat transfer compound should be applied prior to mounting the switch to
ensure good heat dissipation.
