Switch box for power tools with safety systems
First Claim
Patent Images
1. A switch box for use with a woodworking machine having a cutting blade, a motor adapted to move the blade, and a control subsystem adapted to control the motor, the switch box comprising:
- a housing;
a first switch at least partially supported by the housing and configured to switch power to the control subsystem;
a second switch at least partially supported by the housing and configured to trigger the operation of the motor, where the second switch will not trigger the operation of the motor until after the first switch has switched power to the control subsystem; and
a light on the switch box to indicate whether the first switch has switched power to the control subsystem.

Abstract
Switch boxes for power tools with safety systems are disclosed. The switch boxes are particularly useful for woodworking equipment such as table saws equipped with safety systems that detect and react to dangerous conditions. The switch boxes may include a power switch, a start/stop switch, a bypass switch and a visual indicator.

13. A woodworking machine having a cutting blade, a motor adapted to move the blade, and a control subsystem adapted to control the motor, the machine comprising:
-
a first switch configured to switch power to the control subsystem;
a second switch configured to trigger the operation of the motor, where the second switch will not trigger the operation of the motor until after the first switch has switched power to the control subsystem;
a safety system to detect a dangerous condition between a person and the blade; and
a third switch to bypass the safety system. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
