First Claim
1. A touch-sensitive sensor comprising:
- a control circuit board having first and second sides;
a sensor substrate having a connection terminal; and
a resilient electrical connector for establishing an electrical connection between the control circuit board and the connection terminal, wherein the resilient electrical connector is mounted on the first side of the control circuit board and is configured to extend over an edge of the control circuit board and in a direction towards the second side of the circuit board in order to connect with the connection terminal of the sensor substrate.

Abstract
A touch-sensitive sensor comprises a control circuit board and a sensor substrate which are fixed to a cover panel. Electrical connection terminals on the sensor substrate are adjacent an edge of the circuit board. To establish electrical connections between the sensor substrate and control circuitry on the circuit board, sprung electrical connectors are provided. These are mounted on the side of the circuit board opposite the side which is fixed to the cover panel. This allows the circuit board to be fixed flat against the control panel. The sprung electrical connectors are configured to extend over the edge of the control circuit board and are bent towards the control panel so that they resiliently connect with the connection terminals of the sensor substrate. This allows electrical connections to be established automatically as the sensor substrate is put in place during assembly. The sensor may be based on either capacitance or resistance measurements.
