Then the next time the switch is pressed it turns the LED off and it stays off after the bumper is released. An example of this would be pressing the Bumper Switch to turn on an LED and the LED stays on after the switch is released. A Bumper Switch could serve as a toggle switch.Pressing a Bumper Switch could start a conveyor belt system (simulating a factory sorting system) to run for 5 seconds and then stop.User Input: Some examples of user input are: This allows the sensor to be nested within a piece of 1x2x1 C-Channel.Ī Bumper Switch is typically used for three different applications: for user input, for detecting the position of a robot structure, or for detecting a physical object.

The housing of the Bumper Switch v2 has a new narrower profile.Additional components can be mounted to the Bumper Switch using this threaded insert. This screw can be removed and the button removed to reveal a 8-32 mounting insert below. The Bumper Switch’s red bumper button has a screw in the center of it.The Bumper Switch housing has two slotted mounting holes (one on each side) for easy mounting to the robot’s structure.

The new design has some useful and improved design features, these include: The Bumper Switch v2 is a redesigned version of the Bumper Switch which has been included with VEX EDR kits for over a decade. The Bumper Switch is spring loaded so when the force pushing it in is removed, the bumper moves back up to its original position. The Bumper Switch needs to be paired with a programming language such as the VEXcode V5 Blocks or Text to create a user program in order for the Brain to use this returned state to serve as an event or as sensing for a type of feedback control. This is known as a digital state, that is the state is high (1) or low (0). This returns a digital high signal (1) to the Brain. When the bumper on the switch is not pressed, the black wire and the white wire are no longer connected and the circuit is open. When the switch is pressed, the white wire and the black wires are connected returning an active digital low signal (0) to the Brain. The Bumper Switch has three wires connected to it: a black wire- the ground wire, a red wire-not connected, and a white wire - the signal wire. The Bumper Switch v2 is included in the VEX V5 Classroom Starter Kit and can also be purchased as a 2-pack here. In order for the Bumper Switch v2 to be functional with the V5 Brain, the sensor cable needs to be fully inserted into a V5 Brain 3-Wire Port, and the port needs to be configured as Digital In (High) within the 3-Wire Ports menu. Their sensor cable can be extended using a 3-Wire Extension Cable. The 3-Wire Sensors are compatible with the V5 Robot Brain or the Cortex.

This switch requires only a light touch to activate and is one of the 3-Wire series of sensors. The Bumper Switch v2 is a single digital switch with a spring-loaded bumper which can be pushed in to change the state of the switch. Bumper Switch v2 & Limit Switch V5 (3 Wire Sensors) Description
