Abstract

Table saws with safety systems are disclosed. The safety systems detect and react to dangerous conditions, such as contact between the blade and a person. The table saws may include a switch, a first light that illuminates to indicate the safety system is operable, and a second light that illuminates to indicate that the safety system is inoperable. The switch may not power the saw when switched on if the second light is illuminated.

Claims (9)

1. A table saw comprising:

a circular blade;

a motor that spins the blade;

electronics that detect contact between the blade and a person;

a safety system that stops or retracts the blade when contact between the blade and a person is detected;

a switch that is switchable between an “on” position and an “off” position to start and stop the motor;

a first light that illuminates to indicate the safety system is operable; and

a second light that illuminates to indicate that the safety system is inoperable;

where the motor will not begin spinning the blade when the switch is switched from the “off” position to the “on” position if the second light is illuminated and the safety system is not then stopping or retracting the blade.
