| | | Dead-man foot switches | | Elektronic buzzers and horns for automatic train protection systems Elektronic buzzers in the driver's cab of railway vehicles are an integral part ofthe intermittent automatic train-running control and the dead-man equipment respectively. Schaltbau JA222 Series proven buzzers are designed for that purpose. With its electronic buzzer JA224A Schaltbau integrates up to nine differnt warning tones for country-specific train protection systems in an all-in-one device. So the buzzer is suitable for use in multi-system railway vehicles in cross-border service throughout Europe. | | |
