COMMUNICATION SYSTEM, COMMUNICATION METHOD, AND CONTROL DEVICE
First Claim
1. An input device comprising:
- a switch group including at least three switch units formed of at least three movable contacts and at least four fixed contacts, each switch unit being configured to connect or disconnect a pair of fixed contacts selected from among the at least four fixed contacts, by switching corresponding one of the at least three movable contact between a contact state and a separation state, the pair of fixed contacts selected for one of the at least three switch units being different from the pair of fixed contacts selected for another of the at least three switch units such that at least three different combinations of two fixed contacts taken from among the at least four fixed contacts are provided for the at least three switch units,wherein the at least three movable contacts move integrally as a group.

Abstract
If a portable device receives a request signal from a control device that requires a response from the portable device, a first response signal is transmitted from the portable device during a common period defined in all portable devices. Thus, in a case where there is no portable device which enables wireless communication with the control device, a value of received signal strength indication of a wireless signal which is received from the portable device by the control device is very small and becomes smaller than the threshold value during a period in the common period. In this case, the control device suspends reception processing of causing a signal to be transmitted from the plurality of portable devices subsequently to the first response signal.
